    MFI specs

    Plastic stacks are 72-73 2.4E (314)

    Throttle bodies are 38mm top/32mm bottom. If there are any numbers on the front of the housing (vertical area) near the vacuum tube they are '73 2.4E No numbers = '72 2.4E.

    MFI specs

    '72S and '73S and RS plastic stacks are the same part (312). They are about 43.5mm at the top and taper to 38mm at the bottom.

    '73S and RS throttle bodies are the same part and are 38mm at the top and taper to 36mm at the bottom.
